The advanced SureFire SFMB-68-5/8-24 muzzle brake, which fits 6.8 mm rifles with 5/8-24 muzzle threads, greatly reduces both recoil impulse and muzzle rise so that the weapon tracks straight back to keep you on target for faster shot-to-shot recovery. Its patented Impulse Diffusion design minimizes side blast and rear-directed concussion effects. The SFMB-68-5/8-24 also serves as a rock-solid mounting adapter for SureFire SOCOM Series 6.8 mm Fast-Attach® suppressors, the SOCOM556-RC model having placed first in the most extensive and rigorous suppressor testing ever conducted by US Special Operations Command.

When used in conjunction with a SOCOM Series suppressor, the patent-pending design of the SFMB-68-5/8-24 provides multiple bearing surfaces to ensure superior suppressor alignment. A rear labyrinth seal minimizes potential carbon buildup in the indexing system and facilitates suppressor removal after extended firing.

All SureFire SOCOM Series muzzle brakes have blind pilot holes at the 3 and 9 o’clock position to enable fine-tuning of recoil characteristics for individual shooting styles or ammunition characteristics. They also have blind pilot holes at the 6 o’clock position to enable indexing the adapter at bottom dead center, and to pin-and-weld on short-barreled rifles. All that is required is a basic hand drill and appropriate drill bits.

SureFire muzzle brakes are individually inspected for concentricity and alignment, and each is covered by SureFire’s No-Hassle Guarantee.
